Stripping down to her bra and underwear, the brunette beauty tweeted about her steamy day on set, writing, "I caved…Just wrapped a #Maxim photoshoot."

The 23-year-old has been working pretty steadily since Seventh Heaven wrapped, with a recurring role on ABC Family's The Secret Life of the American Teenager in 2010 as well as appearing in several films.

Mackenzie Rosman may have played little Ruthie Camden on the longest running family drama in history, but judging by her recent photo shoot for Maxim's September issue, the former child star is all grown up (let's just hope Reverend Camden approves!). Check out the star's steamy "now" pic on the next slide. [Click to Tweet this!]

Mackenzie Rosman: Now

Stripping down to her bra and underwear, the brunette beauty tweeted about her steamy day on set, writing, "I caved…Just wrapped a #Maxim photoshoot."

The 23-year-old has been working pretty steadily since Seventh Heaven wrapped, with a recurring role on ABC Family's The Secret Life of the American Teenager in 2010 as well as appearing in several films.

Despite her materialistic valley girl character, audiences across America fell in love with Karyn Parsons, who played the beautiful but ditsy, shopping-obsessed cousin on The Fresh Prince of Bel-Air. What does Parsons look like today? In a word: Stunning. See for yourself on the next page!

The sassy star has since appeared sporadically in both TV and film, married director Alexandre Rockwell in 2003, and had two children.

Rider Strong: Then

Better known as: Shawn Hunter of Boy Meets World

No question, it was shaggy-haired heartthrob Rider Strong that had teenage girls across the country totally addicted to 90s cult classic Boy Meets World. The then baby-faced 14-year-old played Shawn Hunter, a Hollywood hottie who had a major bromance with Ben Savage's character Cory Matthews.

Rider Strong: Now

Though he's continued to guest star on high-profile shows like Law & Order: Criminal Intent, Castle, Bones, and Veronica Mars, Strong is now more focused on filmmaking. As a writer, director, and producer of low-budget horror films (which he collaborates on with his brother, Shiloh), one of their projects, The Dungeon Master, took home the "Best Short Film" prize at the 2011 Tribeca Film Festival. And when it comes to love, Rider's been just as lucky, recently becoming engaged to actress Alexandra Barreto in December 2012.

The Disney Channel recently greenlit a spinoff series, Girl Meets World, but much to the dismay of women everywhere, the 33-year-old actor won't be participating (yet rumor has it, there might be a secret reunion in the works—fingers crossed!).

Staci Keanan: Then

Better known as: Dana Foster of Step by Step

Andrea Barber: Then

Better known as: Kimmy Gibler of Full House

It's hard to believe it's been 25 years since the Tanner family first couldn't escape the super-irritating-yet-so-loveable Kimmy Gibler on Full House. After the iconic TV series ended, Barber shifted her focus from acting to academics, getting a degree in English from Whittier College and later receiving an MA in Women's Studies from University of York in England.

Barber found love and married in 2002 and now has two children (a boy and a girl) and works as an assistant to the director of Whittier College's Office of International Programs. But get this: The whole gang from Full House still hangs out together, most recently reuniting for John Stamos' 50th birthday party.

A.J. Langer: Then

Better known as: Rayanne Graff on My So-Called Life

A.J. Langer landed the role of wild and dangerous Rayanne at only 20 years old, and from that moment on, she turned Claire Dane's world completely upside down. Before joining the cast, the actress worked as a regular on a slew of other popular 90s shows like Drexel's Class, Blossom, Hangin' with Mr. Cooper, The Wonder Years, Beverly Hills 90210, and even Baywatch. She continued to work in television after her stint on My So-Called Life with projects like Seinfeld, The Drew Carey Show, Three Sisters, and Eyes.

A.J. Langer: Now

Langer took a hiatus from acting in 2005 to marry Charles Courtenay, an L.A. lawyer and future Earl of Devon. "We met in a bar in Vegas. He didn't know I was an actress. I didn't know he had a castle," Langer told People Magazine. Upon the death of the current Earl of Devon, the two will move into the 14th-century Powderham Castle in England, where Langer will assume the title of Countess of Devon—talk about a fairytale ending!

In 2011, after a six-year acting hiatus, Langer appeared in 14 episodes of Private Practice in the recurring role of Erica Warner, but she left the show in 2012 following her character's death.

Better known as: Vinnie Bonitardi of Blossom and Ted McGriff of Hey Dude

He may be best known for his role as lovable troublemaker Ted McGriff on Nickelodeon's cult comedy Hey Dude, but David Lascher also played the super dreamy on-again, off-again boyfriend of Blossom.

Cherie Johnson: Then

Better known as: Maxine "Max" Johnson of Family Matters

By the time she was cast as Laura Winslow's best gal pal on Family Matters, Cherie Johnson already seemed like a Hollywood veteran. From Days of Our Lives to Punky Brewster, the talented actress had countless projects under her belt and has appeared in a variety of projects since her days on the memorable 90s show. And one thing's for sure: She definitely makes health and fitness a priority in her life. The proof is in the bikini pic on the next page!

The multi-talented 37-year-old does more than act these days, dabbling in both producing and writing. In 2011, Johnson released a poetry book and even has a whopping seven-book publishing deal.

Ian Ziering: Then

Better known as: Steve Sanders on Beverly Hills, 90210

While we loved Ian Ziering as the ultimate ladies man on Beverly Hills, 90210, he's even more handsome today (minus that cheesy curly hair of course).

Ian Ziering: Now

The now 49-year-old actor has managed to stay somewhat busy in the biz, including a stint on Dancing With the Stars in 2007 where he made it all the way to the semi-finals. Who knew Steve had such sweet moves! Apparently dancing is something the Hollywood hunk stayed with, as he made a guest appearance earlier in 2013 with the Chippendales (shirtless and sexy, we might add) in Las Vegas for four whole weeks.

"Actors and performers never know what their next job will be, and when I got the call from Chippendales, my jaw dropped as it came on the heels of TMZ calling me fat on national TV," the star told US Weekly. "I am passionate about health and fitness, so I've kept in shape, and dancing is something I've always enjoyed, so I figured why not? ...It's really a dream come true!"

When it comes to his love life, Ziering married Erin Kristine Ludwig, a nurse from Ohio, in 2010. The adorable couple has two girls (Mia Loren, 2, and Penna Mae, 5 months) who happen to share the same birthday.

Better known as: Marcus "Mark" Jason Taylor on Home Improvement

Taran Noah Smith: Now

Although the now 29-year-old actor has gotten out of the business, he's managed to stay in the press—unfortunately not in a good way. In 2001, Smith sued his parents over the 1.5 million he had saved in a trust fund, alleging they used it to buy a mansion.

Also that year, at the age of 17, he married Heidi Van Pelt, which sparked a lot of controversy at the time because she was 16 years his senior. The pair opened a vegan restaurant called "PlayFood" in California and had a son, Nolan Eric Smith, before divorcing in 2007.
